Information about the operating mode of decomposition during cooling to various T q were gained by SAXS method. After reaching the T q wanted the samples were quenched into water of RT and the SAXS intensity curves were measured at RT. Strong evidence was found that below about 175 °C the decomposition starts in this alloy with the nucleation and growth of Guinier‐Preston zones. As proved by other authors, 175 °C is the upper limit temperature T rhm for the onset of the rapid homogeneous nucleation of precipitates.
